Orig nal application February 26, 1943, Serial No. 477.203. Divided andthis application March 24, 1944, Serial No. 527,878

3 Claims. (Cl. 229-34) This invention is a division of my applicationSerial No. 477,203, filed February 26, 1943, and relates to collapsiblecontainers of the casing and drawer type adapted to co-act to form filecabinet sections which may be stacked one upon the other and moreparticularly to structures comprising non-metallic materials.

A drawer of the class described is shown in my Patent No. 1,946,516issued February 13, 1944, such drawer being fashioned from a cut andscored corrugated board blank, as fully described therein.

The object of my invention is the provision of structural elements forcollapsible drawers wherein facing may be applied to the drawer front ina secure and novel manner.

Figure 1 is a bottom view of the blank for forming the drawer,substantially as shown and described in my Patent No. 1,946,516.

Figure 2 is a cross-sectional view taken on line 2-2 of Figure 1 lookingin the direction of the arrows.

Figure 3 is a front view of the front panel of the drawer before thereinforcing facing sheet is secured thereto, the outline of the facingsheet being shown in dotted lines.

The front panel of the drawer may be finished off in any suitable mannerin order to improve the appearance thereof. While in prior collapsibledrawer construction, such as that shown in my Patent No. 2,152,676, ametal facing sheet was utilized, owing however to the scarcity of metalfor the ordinary file cabinet construction uses at the present time, Ihave devised a method for facing the drawer front by means of a fibersheet, preferably a pressed paper board such as hard board or the like.The front panel I49 of the drawer of Figure 1 has secured to the outerface thereof a hard board facing sheet I 50. This sheet, as will benoted particularly in the cross-sectional view of Figure 2 extendsbeyond the boundaries of the,front panel, so that when the drawer isfolded up into erected condition, the extending hard board sheetprovides a rabbeted formation which may bear against the front end of acontainer, as shown in my Patent No. 2,152,676.

The facing sheet I50 may be secured to the front panel in any suitablemanner, preferably by adhesive. However, as the drawer is pushed intothe casing, the abutment of the outer edges in the bottom surface of thefront wall I49. tabs being foldable at the fold lines joining panel I49with the side wings and the drawer bottom.

The tabs I60 are bent outwardly into approximately the plane of thefront panel I49 so that the tabs I60 thus form extensions as shown inFig. 3. The facing sheet I50 is then secured over the front surface I49and to the tabs I60 which project beyond the boundaries of the frontsurface. When the drawer is now forced in so that the front thereofbears against the reinforcements, the striking force against thereinforcement is taken up against the tabs I60 which are securedrespectively to the side wings and the bottom wall and which in turncarry the facing sheet I50.

. Since these tabs I60 are thus substantially integral with the drawersides and bottom, the force necessary to tear them off would be muchgreater than the force needed merely to remove the adhesively securedpanel I50 of the drawer front. In addition, no force need be taken up bythis adhesive securement of the facing sheet I50 since the tabs I60 takeup this impact.

Accordingly, by this means accidental removal of the facing sheet I50 isprevented. Y In the foregoing I have set forth my invention inconnection only with preferred embodiments thereof. Many variations inthe formation of the various elements and in the adaptation thereof tovarious collapsible structures should now be clear to those skilled inthe art. I therefore prefer to be bound not by the specific descriptionsherein set forth, but only by the appended claims.

I claim:

1. A drawer front comprising a panel having an exterior face; a bottomwall connected to said panel; and side wall members connected thereto;at least one tongue cut out of said panel adjacent said bottom wall aIndeach of said side wall members; said tongues being connected to saidside wall members and said bottom wall and being folded through into theplane of said panel and extending beyond the edges of said panel; afacing sheet secured to said panel 'and said tongues, said facing sheetbeing disposed on said exterior face of said panel whereby to form thefront of said drawer and said tongues being secured to said facing sheeton the side thereof contiguous with said exterior face, wherein saidfacing sheet is substantially similarin shape tq said panel and ofsufficient dimension to provide a marginal boundary when said facingsheet is secured to said panel, said tongues being secured to saidmarginal boundary. A

2. A drawer front comprising a panel an exterior face; a bottom wallconnected to said panel; at least one tongue out out of said;

is substantially similar in shape to said panel and of sufficientdimension to provide a marginal boundary when said facing sheet issecured to said paneL said tongue being secured to said marginalboundary, V

3, A drawer front comprising a panel having anexterior face; abottqrnwall connected. to said panel and side wall members 1 connecte dthereto; at least one tongue cutout of said panel adjacent a side wallmember; said tongue being connectedlto said side wall member, and beingfolded thrw h .l i i ii ane than Panel and extending beyond the edge ofsaid panel; a facing sheet secured to said panel and said tongue, saidfacing sheet being disposed on said exterior face 'of said panel wherebyto form the front of said drawer and said tongue being secured to saidfacing sheet on the side thereof contiguous with said exterior face,wherein said facing sheet is substantially similar in shape to saidpanel and of sufficient dimension to provide a marginal boundary whensaid facing sheet is secured to said panel, said tongue being secured tosaid marginal boundary.
